中文摘要 | 傳統數學課程的角度單元是靜態的,而且不易操作,因此學習成效不佳。本研究利用電子幾何板(Geometer's Sketchpad),以生活實例出發,設計動態視覺化角度學習活動單元,並探討五年級學生在動態情境中,由滑鼠操控虛擬的量角器及角物件,並可輸入參數數值控制角度大小等行動,進行角度的實測及估測學習,進而改善傳統靜態課程不易融入操作行動的缺點。為深入探討學生表徵能力和概念的發展及學習成效,本研究僅採取一位個案進行補救教學實驗。經由比較前、後測成績、分析學生的學習單及進行訪談後,其研究結果顯示,利用所設計的電腦活動進行角度單元補救教學,確實可以增進學生的測量能力。 |
英文摘要 | Students cannot act well directly in the traditional mathematics curriculum for the angular lesson therefore perform poorly in consequently. This study construct dynamic visual activities for learning the angles lessons in the Geometer's Sketchpad computer software. In the constructed activities, user can manipulate the virtual angular measurement tool and input the parameter to control the size of angles. Since the student can act and reflect from her action, hence she has much opportunity to learn the measurement and estimates concepts better than before. A fifth grader was chosen as subjects who did not do well on the angles units test. This subject was carefully studied how she constructed and represented the concepts of angles and how she performed in the level of cognitive development. The results did show that the subject improved on the ability of angular measurement. |
